Scenario 2 – Maximum number of Full Res video sources on a tiled display
Screen Layout
12 UXGA display devices are used to create a 4x3 tiled display. 48 video source windows are
arranged as an 8x6 array. The total display size is 6400x3600 pixels, making each window 800x600
pixels.
Because each window is larger than the native source resolution, each source is transferred across
the RAPT at its native resolution and then scaled up to the required size by the Output Card.
Hardware Requirements
6 Output Cards (driving 12 UXGA screens)
4 Input Cards (providing 48 source inputs)
An ES3301-2 Card Frame.
System Capacity
The limit of 48 real-time source windows is imposed by the available RAPT bandwidth and the
available screen space. This assumes that all sources are using single-field de-interlace and are
sampled at 4:2:2.
Expansion Options
There are five spare card slots so you could add further Output Cards to add more screens or further
Input Cards to increase the choice of sources.
Increasing the number of full resolution source windows will exceed the real-time limit of the RAPT
bus, so VN-QUANTUM will implement its bandwidth management scheme.
